# Build configs This directory includes configuration files (json) for the tasks/build.js build script. Notes: `use_types_for_optimization` is set to `false` for the SIMPLE and WHITESPACE builds. If it was set to `true` we would get function names like `ol_control_Control_prototype$setMap` in the compiled code when using the SIMPLE compilation. `use_types_for_optimization` is only appropriate for ADVANCED compilation. To be sure we also don't set it for WHITESPACE.
